Hi Richteb.
A friend of mine loaded these Woodlieghs in his .375 last year for use on our Aussie buff and reported excellent results.
The thing to remember with the Woodleighs is that they should only be loaded to the velocities reccomended on the pack.
When driven faster than the design speeds, they flatten out like a coin and do not penetrate very far, something we see on a semi-regular basis with the 416 Rigby users who are handloading the Woodlieghs at 2500 +.

The 350gn gives a little boost to your standard .375 and if you put that Woodliegh in the right spot you will hear your bull bawl, " awe, good shot mun".
